The ratio of the speeds of a car and a bus is 3 : 4. If the bus covers a distance of 320 km in 4 hours, what is the speed of the car (in km/h)?
60 km/h
Step 1 — speed of the bus:
\(\text{Speed}_{\text{bus}} = \dfrac{320}{4} = 80 \text{ km/h}\)
Step 2 — apply the ratio. Car : Bus = 3 : 4, so:
\(\text{Speed}_{\text{car}} = \dfrac{3}{4} \times 80 = 60 \text{ km/h}\)
Hence the car's speed is 60 km/h.
